Abstract

A filament feeding mechanism for a 3D printer head for selectively feeding filaments, comprising a motor wheel (1) for feeding filaments, and a set of pinch rollers (2, 3) mounted on a rocker arm (4). It further comprises a pushrod (8) connected to the rocker arm (4), and in that the rocker arm (4) is pivotably mounted with the axis of rotation (5) and adopted to rotate by lateral motion of pushrod (8) to press one of the pinch rollers (2, 3) to the respective filament.

Claims

8 AMENDED CLAIMS received by the International Bureau on 31 July 2018 (31 .07.2018)
1. A filament feeding mechanism for a 3D printer head for selectively feeding filaments, comprising a motor wheel (1) for feeding filaments,
and a set of pinch rollers (2, 3) mounted on a rocker arm (4)
characterised in that
it further comprises a pushrod (8) connected to the rocker arm (4) and is adapted to lowering the printing nozzle (15) while the second nozzle (14) is stationary, and in that the rocker arm (4) is pivotably mounted with the axis of rotation (5) and adopted to rotate by lateral motion of pushrod (8) to press one of the pinch rollers (2, 3) to the respective filament.
2. Mechanism according to claim 1 wherein the rocker arm (4) has a leading wheel and pushrod (8) has an opening guiding the leading wheel (7) of the rocker arm (4) to rotate the rocker arm (4) by lateral motion of pushrod (8).
3. Mechanism according to claim 1 or 2 wherein the rocker arm (4) is adopted to be actuating by the tooth wheel arrangement (22, 23).
4. Mechanism according to any of claims 1 to 3 wherein the rocker arm (4) comprises an U-type groove for a motor wheel (1), and pinch rollers (2,3) are mounted on both sides of motor wheel (1) on the U-type groove arms.
5. Mechanism according to any of claims 1 to 4 wherein the rocker arm (4) comprises an oval opening for a motor wheel (1) and filament guiding channels (24, 25) creating a pinching volume where filaments are pressed to the motor wheel (1) by the pinch rollers (2,3).
6. Mechanism according to claim 5 wherein at least one pinch roller (2, 3) is spring loaded.
7. Mechanism according to any of claims 1 to 6 wherein the pushrod (8) is provided with pressing element (9) for lowering the printing nozzle arrangement (13, 15) when the respective filament is fed to the nozzle (15).
8. Mechanism according to claim 7 wherein the nozzle arrangement (13, 15) is further provided with a rest spring (16) for lifting the nozzle arrangement (13, 15) when nozzle (15) is not fed with filament.
9. Mechanism according to any of claims 1 to 8 wherein the rocker arm (8) is a modular assembly.
